Tributes were pouring in on Sunday for the six hostages who were found dead in southern Gaza over the weekend.

The hostages, whose bodies were retrieved from a tunnel, ranged in age from 23 to 40. Five had been at a dance music festival in southern Israel when they were taken captive during the Oct. 7 attack on Israel by Hamas and its allies; a sixth was taken from the village of Be’eri.

The Hostages and Missing Families Forum, a group of their relatives, identified the dead as Carmel Gat, Eden Yerushalmi, Hersh Goldberg-Polin, Alexander Lobanov, Almog Sarusi and Ori Danino.

They were among the roughly 100 hostages remaining in Gaza, both dead and alive. Here is what we know about them.

Hersh Goldberg-Polin, 23

Mr. Goldberg-Polin was a dual Israeli American citizen who was taken hostage from the festival in southern Israel on Oct. 7. His mother, Rachel Goldberg-Polin, had traveled the world since, advocating the release of the hostages.

“Hersh is a happy-go-lucky, laid-back, good-humored, respectful and curious person,” she said earlier this month, when she spoke at the Democratic National Convention with her husband, Jon. “He is a civilian. He loves soccer, is wild about music and music festivals, and he has been obsessed with geography and travel since he was a little boy.”
